TEDDER Filed Aug. 22, 1929 2 Sheets-Sheet l June 14,1932. H. HURLIMANN TEDDER Filed'Aug. 22, 1929 2 Sheets-sheet 2 Patented .lune 14, 1932 UNITED STATES HANS HRLIMANN, OF KIRCHBERG, SWITZERLAND TEDDER Application led August 22, 1929, Serial No. 387,746, and in Switzerland August 28, A1928.

The present invention relates to improvements in tedders for shaking up the grass or the hay tv hereby expediting the drying thereof.

The main object of the invention is to provide a tedder which might be used to shakeup the grass which has been cut by a mowing mach'ne or mowed by hand labor and lying in swaths or in heaps.

A further object of the invention is to provide a tedder which may be used as an attachment for mowing machines of any conventional type to shake-up the grass immediately after cutting or which can form a machine per se moved by draft animals or tractors.

A still further object in the provision of a device which after having det-ached certain parts can be used to turn hay or/and to turn and spread swaths made by side delivery rates.

l attain these and other objects by a device which lifts the grass from the ground and throws itto the ground again, an oscillating shaking implement be'ng arranged in the path of the falling grass and moving across the path of the grass reciprocating at a suitable speed either in horizontal plane or in any other suitable plane.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in the figures.

In the drawings two tedders according to my invent-ion are shown in al diagrammatical manner.

Fig. 1 is a side elevation of the first form of construction,

Fig. 2 is a top view thereof,

Fig. 3 is a side elevation of the second form of construction,

Fig. 4 is a top view thereof,

Fig. 5 shows the means to reciprocate the shaking implement,

Fig. 6 is a detail elevation partly in section evently over all the members.

of the ball and socket joint between the members 3, 40,

Fig. 7 is a detail plan of the member 12, shaft 4 and connecting mechanism,

Fig. 8 is a detail elevation of one of the front wheels and its operating connections.

1 denotes a frame running on wheels 9, 13, which frame 1, can be attached to a mowing machine or to a tractor or which can be provided with a draft attachment'to be drawn by animals. The wheels are made and mounted in the usual manner in hay making machinery. In the frame 1 a number of shaking members 3 are arranged close and parallel to each other. The rear end of each member 3 is linked to a lever 40, preferably by a ball and socket 46a as shown in detail in Fig. 6, and all the levers 40 are rotatably mounted on a shaft 2 fixed to the frame 1. The fore end of each member 3 is provided with a fork adapted to take grass from the ground. Each member 3 is mounted on a crank of a crank shaft 4 rotatably mounted in the frame 1 beneath said members 3 and running at right angles thereto. The crank shaft 4 is driven from the shaft 8 of the wheels 9 by means of a pair of bevel wheels 7 shaft 6 and a second pair of bevel gears 5. The different cranks on which the members l are mounted are set at equal angles with reference to each other. On the members 3 racks 14 are provided to retain the grain, which is being moved upwards by the action of the members on rotation of the crank shaft 4.l The grass which is being fetched by the forks 41 is thrown upwards on to the members and is moved step by step up to the upperV end, ofthe members 3. The members 3 moving up and down and at different times tear the grass asunder and spread it At the hind end of the machine a fork 12 is arranged projecting inthe path of the grass'falling down from the hind ends of the members 3,

The fork 12 is reciprocated laterally in a horizontal plane between the limits denoted lby broken lines (Fig. 2) and serves to dis- 1 of the tedder.

4 has a crank 4a and a rod 10 is connected at one end to the Wrist of said cra-nk as at 1()a and at the rear end is connected t0 the arm 15 as shown in Fig. 7.

In the construction shown in Figs. 3 to 5 a drum 20 is rotatably mounted in the frame The frame 1 is mounted on wheels 13, 23, of which the wheels 13 are adjustable in height by means of castor pintles 13a, bell crank lever 13", rod 13c and lever 13d as shown in. Figs'. 1 and 8. The drum 20 is provided with several rows of tines 21 which catch the grass from the ground and throw it along a hood 22 of sheet metal. The hood 22 runs concentric to the shaft 30 of the drum 20 and the grassv is thrown upwards and backwards by the aid of sai-d hood. The drum 20 is driven by the rear shaft 2'3a on which the wheels 23 are fastened by means of a train. of spur wheels 24,25-, 26and 27 the spur wheel 27 being keyed on to the shaft 30, the gears 25 and 26 are rotatably mounted on studs ofthe frame 1. On the shaft 30 a disk is fixedI carrying a crank pin 31. Said crank reciprocatesf a lever 33 by mean-s of a connecting rod 32. The vertical arm. of said lever engagesin a slot 34 of a bar 35, on to which the arms 36 of shaking members 28 are'linked. The members 28 are pivoted at 37 on aI crossbar 38 of the frame 1. The free ends of the members 28 proj-ect in the path of thel grass thrown backwardly by the drum and by reciprocating themembersz28 spread the grass While it is falling.

In both of the examples shown and describedthe parts 1-2 or 28Y might be' done away with, and the tedder might be used to turn hay, etc.

The number and position of the shaking members can be varied to suit the length of the grassto` be worked, etc` IVhatY I wish to claim and secure by the U. S. Letters Patent, is

1. A tedder comprising in. combination a frame, wheels supporting said frame, means tolift grass from the ground. and to throw i-t backwardly, shaking means-proj ectin'g in the path of the falling grass andvreciprocatingin horizontal planes.'

. V2. A tedder comprising in combination a frame,.wheels supporting said frame, a. number of parallel slanting feeding members, a crank shaft support-img said members, a crank. for each of said members, the cranks being set at anglesapart, forksl at the lower end of said members, links connectingv the upper end of sai-d. members to a cross rod, a fork mounted: in the frame to swing in a horizontal' plane, and means to reciprocate said fork.

In testimony whereof I aflix my sig-nature.

HANS HRLIMANN.
